HUMBLE, Texas (KPRC/NBC) - A Texas teenager has been accused of forcing a 10-year-old boy to smoke synthetic marijuana on school property, according to authorities.

Humble Independent School District police said the incident happened at Maplebrook Elementary School on Sunday.

Authorities said Christopher Stoneking, 18, approached his 10-year-old neighbor to smoke Kush, synthetic marijuana. Stoneking is accused of holding the boy to the ground and saying he wouldn't let him up until he smoked the Kush.

The 10-year-old witness told investigators Stoneking threatened to hit him if he tried to stop him. That's when Stoneking lit a pipe, put it into the victim's mouth and forced him to smoke.
